Our TEM technology

The Transient Electromagnetic (TEM) geophysical survey method is a modern technique designed to measure vertical resistivity profiles with particular sensitivity to conductive materials.

  • Non-invasive method using wire loops to transmit and receive signals
  • Achieve depth measurements of up to 600 meters
  • Particularly sensitive to conductive materials
  • Leaves no trace on the survey site after data collection
  • Highly efficient, requiring a transmitter loop and one or two smaller receiver coils
  • Entire process takes only a few minutes, from setup to resistivity modeling

Where to use TEM

TEM surveys are highly versatile and are particularly effective in the following areas. Our instruments deliver accurate, fast data to solve many geophysical challenges.

Groundwater Exploration: Identifies freshwater reserves, saline water, and contamination zones to optimize well placement and drilling depth.

Mineral Detection: Locates mineral deposits based on their unique resistivity signatures.

Geological Mapping: Reveals the subsurface structure for various geological studies.

Environmental Surveys: Assesses contaminants and salination in the soil.

The benefits of TEM

Transient Electromagnetic (TEM) mapping is a non-invasive method that ensures that survey areas remain undisturbed, as it uses wire loops to transmit and receive electromagnetic signals without leaving physical marks on the terrain.

TEMcompany geoscanners enable fast, accurate geophysical data collection alongside easy instrument setup, delivering significant time savings for consultants, contractors, and clients.

We've wrapped up the field work here in Kakuma. You guys have really built an incredible system. The Kenyans, with no geophysics experience, can collect data without support after maybe 2 or 3 sites. One of them asked if sTEM stood for simple TEM because it was so easy.

It’s so refreshing to buy an instrument from a group and have amazing support - it doesn’t happen often these days! Your team’s messages were incredibly helpful, well beyond what I could have provided.
